Question

Quizplus · Accepted Answer

A polar covalent bond is a covalent bond in which the electrons are not shared equally between the two atoms. This can happen when the two atoms have different electronegativities, which is a measure of how strongly an atom attracts electrons. In the case of C-Cl, carbon has an electronegativity of 2.5 and chlorine has an electronegativity of 3.0. This means that chlorine will attract the electrons in the bond more strongly than carbon, resulting in a polar covalent bond.
